Hi, the window thumbnails that show up when hovering the cursor over an icon on the task manager are not stacked vertically with a vertical panel. Instead, they are being aligned horizontally. On Windows 7/8/8.1/10, the window thumbnails are stacked vertically with a vertical taskbar, so that would be the expected behavior. Could you please fix it or add an option to make the window thumbnails stack vertically instead of horizontally? Regards
The Task Manager tooltips were rewritten from scratch for Plasma 5.9. Among many other improvements, they also stack vertically now for vertical panels. PS.: Since I've seen you do it in a few tickets now - we don't really care about what Windows does. It's best to ask/argue for changes on their own merits.
